SPECIFICATION forming part of Letters Patent No. 348,779, dated September 7, 1886.

Applicalion filed June 17, 1886. Serial No. 205,411. (No model.)

To all whom it may concern.-

Be it known that I, J onn SABOLD, a citizen of the United States, residing at Little Oley, in the county of. Berks and State of Pennsylvania, have invented certain new and useful Improvements in ingot-Molds, of which the following is a specification.

My invention relates to a mold for casting metal into ingots, and has for its object to provide an improved sectional mold provided with special clamps, as hereinafter specified.

In the accompanying drawings, which illustrate the invention, Figure 1 is a front broad side view of the mold and clamps. Fig. 2 is an edge or narrow side view of the mold andelamps. Fig. 3 is a rear side view of the upper end of the mold and clamps. Fig. 4 is an end view of the mold and clamps,showing the two mold-sections loosened. Fig. 5 is a View 'of the clamp-lever. Fig. 6 is a view of the adjustable tightening-rod Figs. 7 and 8 are views of the pivoted bars which bind the two mold-sections.

The letter A designates one section and B the other of a metal mold. These two sections comprise the broad sides of the mold and unite at the center of the narrow side. Each section has an overlapping edge,c,at each narrow side. (Shown in Fig. 4.) The shape of the interior of the mold is shown in Fig. 4. The interior broad sides, d, are smooth, flat, and parallel with each other, and the narrow sides 0 are a little concave, or, in other words, commencing at each broad side they spread or flare slightly toward the center overlapping edge 0. This shape of the interior, it will be seen, facilitates the release or discharge of the ingot when the two sections A B are loosened or unclamped. Each narrow side has tapered tongue and groovelugsff, the tonguefbeing on one section and thegroove part f on the other section. This device insures that the two sections will always come together in exactly the same position, and thereby the clamping parts on the two sections, hereinafter described, will be sure to have the proper relative position. Each outer corner of the two sections is beveled, as at g, and binding-bars H H clamp the two sections together. Each binding-bar has one end pivoted at h to one section, A, and near the other end has a beveled or inclined shoulder, g, which comes in contact with the beveled outer corner, g, of the mold. The free end of one binding-bar, H, has a boss, h, with a hole through which the screw-threaded end 5 of the tightening-rod L passes, while the free end of the other bindingbar, H, has a wrist, 7s,whereon the lever n is jointed. A lug or shoulder, j, is cast 011 the corner of the mold section B,

and serves to sustain the free end of the binding-bars H and H. Two clamp devices are employed, and each one embraces the bindingbars H H, tightening-rod L, and clamp-lever n, all make ot'wronght-iron. The clamp-lever n has two holes,7.': and 0. The hole 75 1 s for the wrist k on the free end of binding-bar H, and the hole 0 is for the pivot 0, which connects the upturned end p of the tightening-rod L. XVhen the free end of the clamp-lever n. is up, as in the case of the top lei er of Fig. l, the tightening-bar pivot 0 is lower than the wristpivot k; but when the free end of the clamp lever is down, as in the case of the bottom lever of Fig. 1, the tightening-bar pivot 0 has an elevated position, and is as high as or a little higher than the said wrist-pivot, whereby the inclined shoulders g of the binding-bars are in loose or easy contact with the beveled corners g, and when the free end of said lever is forced down, as shown at the bottom of Fi 1, the said inclined shoulders are crowded hard against the beveled corners g, and thereby clamp or bind together the two sections A and l).

The effect of turning the clamp-lever a up vertically, as indicated by broken lines in Fig. 1, is to spread the two binding-bars H and H away from the narrow sides of the mold, as i11- dieated by broken lines in Fig. 4, and thereupon the two mold-sections A and B will be loosened or separated and the ingot will drop out easily. The two binding-bars at each narrow side are pivoted by one and the same rod, q. At the top each section has a loop or eye, 9', by which the mold may be lifted. The wrought-iron clamps on the outside give great strength to the mold, and they will spring or give sufficiently to allow of the expansion due to the heat of the ingot-castin Tli'e mold clamped in this manner may be made of closer and harder metal than would be possible otherwise. The clamp-lever arrangement is both powerful and quick-acting.

The shape of the ingot which this mold will produce being broader one way than the other, with parallel sides, (not tapered,) facilitates its reduction under rolls. The shape ofthe ingot, to wit-comparatively thin one way-favors its rapid cooling and avoids heating the mold excessively.

Constructed as here shown, the parts require little or no special fitting up.

Having described myinvention, I claim and desire to secure by Letters Patent of the United States- 1. An open-topped mold for ingots,made in two sections, A and B, separable at the two narrowest opposite sides,with interior parallel broad sides, (1, and interior narrow sides, 0, which are concaved at the center separable edges, 0, and the outside clamp consisting of the binding-bars H H, tightening-rod L, and clamp-lever n, as shown and described.

Mai-79 .2. The combination, in an open-topped mold for ingots, of two mold-sections, A and B, separable at the center of two opposite sides, and said sections having outer beveled corners, g, a binding-bar extending across the separable part of the two sections, having. one end pivoted to one section and provided near the other end with an inclined shoulder, g, to come in contact with one of said beveled corners, a tightening-rod, L, having one end turned up and the other end connected with one bindingbar, and a clamp-lever, a, pivoted to the other binding-bar, and also pivoted to the turnedup end of the rod, as set forth.

In testimony whereof I a'ffix my signature in the presence of two witnesses.

JOHN SA BOLD.
